Evaluation ,advantages and disadvantages of Milking machine

Milking Machine  Milking machine design and function is critical for

rapid and efficient removal of milk without damage to the teat or gland.  Minimal risk for transmitting pathogenic microorganisms that might cause mastitis

Principle of Milking Machine ¤ Its based on Vacuum supply(Negative pressure) and Pulsation. ¤ Vacuum supply(Negative pressure) = 11-14 inches of Hg ¤ Pulsation rate= 50-60 cycle per minute ¤ Negative pressure and Pulsation helps to remove and move down milk from udder. ¤ Negative pressure open the teat canal through partial vacuum. ¤ Pulsation also help in massages the teat.

Types of Milking Machine

¤ Hand operated Milking Machine Mechanically operated by handle Avilable in cheaper cost Generally use in small dairy farm or house hold use

¤ Electric Motor Operated Milking Machine Electrically Operated by motor Generally use in small dairy farm

Applying of Machine And Precaution ¤ Regularity of time and routine required. ¤ Before starting milking properly wash udder and teats with clean water. ¤ Massage the cow’s udder and Dry udder and teats. ¤ Use strip cup to remove few streams of milk. ¤ Applying teat cups and checking teat cup placement proper or not.

Machine-on time : ¤ Maximal intra mammary pressure caused by milk letdown occurs at about one minute after udder preparation begins and continues for about 5 minutes. ¤ Most cows will milk out in 5 to 7 minutes

Detaching the machine at the end of milking ¤ The vacuum must be turned off before the machine is removed. ¤ Otherwise, pulling on the teat cups while the vacuum is still on may cause trauma to the teat ends. ¤ Shut off vacuum and remove unit when milk flow. NOTE:¤ Washing the machine between every milking. ¤ Treated and sick cows shall always be milked separately and after all the healthy cows.

Benefits of the Machine Milking ¤ First of all, it allows the dairy farm to increase their activity with a larger herd. ¤ In machine milking the peak yield is achieved quicker and remain longer so total yield is more. ¤ Its avoid contamination of outside –bacteria and foreign material.

Benefits of the Machine Milking ¤ Minimum irritation to the udder, teats and tissues. ¤ Its easy to operate ,save time and labour expenses. ¤ Prevent invasion of external organisms . ¤ Proper milking machinery can manage herds faster while ensuring the quality of the milk. ¤ Milking machinery also reduces the farm’s dependency on workers.

Disadvantages of Milking Machinery ¤The most obvious disadvantage will come with older cattle. That's normally used to hand milking. ¤Older cows will have trouble adjusting to automatic milking machinery. ¤ This may increase their stress levels and reduce their milk quantity and quality.

Disadvantages of Milking Machinery  ¤Secondly, the machinery will need a constant

supply of electricity.  ¤This means that in cases of damages to the power supply system the dairy farm will not be able to operate properly.  ¤ Its also require emergency power supply systems.  ¤ Milking machinery require strict cleaning procedures.  ¤ Because of improperly cleaned machinery can lead to infections.
